I’ve been using the QiDi 4 Max 3D Printer with the 4 color combo box, and it’s been an excellent experience overall. Print quality is outstanding. Layer lines are clean, details are sharp, and results look professional with minimal tuning. Speed is equally impressive, delivering fast prints without sacrificing quality, which makes larger or multi part projects much more efficient. The large build volume is one of the biggest advantages. Not being limited by size feels incredibly freeing and makes it easy to take on bigger projects without splitting models. Compared my previous print, the Prusa i3 MK2, the build quality here feels much more solid. I was nervous the print quality would not be able to match the Prusa but I am happy report it is just as good if not better. The features and enclosed printing are above and beyond what I expected for a printer in this price range, and the ability to reach high temperatures opens the door to high strength materials, making it an engineer’s dream. The 4 color combo box adds great flexibility for multi color prints without making things overly complicated. Overall, this setup delivers an excellent balance of speed, quality, and capability at a fantastic cost point. I would not hesitate to purchase this printer again

I previously owned the QIDI Q2 and absolutely loved it, so I already had a lot of confidence in QIDI’s printers. When I saw that the MAX4 offered a much larger build size, it made perfect sense to pick one up for bigger projects and larger prints. What stands out the most is how incredibly well it handles detailed prints, especially figures. The level of precision and consistency it delivers makes a huge difference when working on models where fine detail really matters. Another thing I really appreciate is how seamless everything feels. From setup to everyday use, the printer just works without constant tweaking or troubleshooting. The interface is intuitive, and the overall workflow is smooth, which makes it easy to focus on creating rather than fixing issues. Overall, the MAX4 has been reliable, high-quality, and surprisingly user-friendly for such a capable machine. If you’re into printing detailed figures or want the flexibility to handle larger builds without sacrificing quality, this one is definitely worth it.

The QIDI Max 4 has delivered very good print quality overall. Once everything was working correctly, the printer handled long prints reliably and produced consistent quality across different materials. So far I have printed PLA, PETG, and ASA all printed flawlessly with excellent quality. However, I did experience some setup and software-related issues initially. When the printer first arrived, it had a poor Wi-Fi connection and faulted during the update process without displaying an error message. After attaching and updating the Qidi Box, I started experiencing MCU Connection errors that caused random failures during longer prints. The error popped up with a QR code to diagnose the issue, which stated that it was most likely a cable issue. luckily II had a second box which i attached and more MCU errors arose. Fortunately, I was able to find a post that someone had the same issue and it was due to a firmware mismatch. After updating the firmware again the MCU errors went away. The printer produces great results although there are still software/connectivity issues. Qidi studio will not stay connected nor will the Qidi Maker app. which definitely needs improvement and the printers software needs better error handling. That said, the actual print performance and print quality are excellent, and overall I’m very pleased with this printer. With this being a new machine I am sure there will be updates that will address these issues. When I first got my Q2 it had similar initial issues but once resolved it has run for 12-16hrs a day for the last 4 months without any problems.

This a huge and excellent machine. Aside from the size, set up is easy. Even someone with no experience should have no issues. Follow the on screen prompts on the machine and it walks you through everything. Build quality is excellent. Little details and quality of life features in everything from a proper driver to remove packing screws to the status bar led in the base of the build plate. This machine is well thought out and also just plain looks good. The Qidi Box is easy to hook up as well. No issues there. First prints out of the box (waste chute and bin) with generic PETG settings came out fantastic. I am looking forward to doing large multi color prints in all materials. This thing is a beast in all the best ways. LOVE IT. This is my second try at leaving a review. Not sure if the first one went through or not. If I end up with two on here, sorry.

This printer has been absolutely awesome! I also have a Qidi Plus 4 and have absolutely loved it, but the Max4 is as if they took all the suggestions for improvement on the plus 4 and added them to the Max 4. Its bigger and better and its been flawless so far! Been printing everything from pla to ppa-cf on it and its been amazing! First layers have been absolutely perfect and I dont even have to question if the print is going to come out flawless or not, it just puts in work print after print. Really glad I decided to get the Max4 and im excited to continue printing on it! If you're questioning getting one, absolutely get yourself one! Here's some pictures of different things i printed on it

Waited almost 2 months for this printer to arrive and it is well worth it! The quality of the machine and the ease of setting it up was easier than any other printer ive setup before. Beware though, it is HEAVY!!! Do not attempt to lift by yourself. Make sure to update the firmware immediately upon installation before you even try doing a test print. The firmware fixed a lot of bugs that were still present being that it is a new release. I own one other qidi machine (x-plus first generation) that I purchased 5 years ago from here on Amazon and its still printing with no problems to this day. I cant say enough about how helpful the support team over at qidi is if you have any type of question or troubleshooting situation. Will continue to buy qidi products.

Superb print speed and quality right out of the box. Super simple to set up with very little need for instructions. After the printer completed firmware updates, bed leveling, etc... I tested with a benchy boat print. The print completed within 20 minutes without issue. One of many great products from Qidi. Qidi also has a great support center who have assisted me with previous firmware issues and part replacement. Very knowledgeable and very quick to respond.

I started out on a flashforge dreamer nx and this in night and day so to speak. I'm very impressed with the whole thing even the slicer that it comes with. Multi colored not so much alot of poop,but with large build area and a lot of little parts it would be okay. Over all I'm very happy
